Insights
The Braile Vena Cava filter (VCF) demonstrated safe implantation with minimal asymmetry and no migration. This filter offers improved embolus capture and symmetry compared to older models.
Area of Science:
- Vascular Surgery
- Medical Device Evaluation
- Interventional Radiology
Background:
- Vena Cava filters (VCFs) are crucial for preventing pulmonary embolism.
- Assessing the safety and efficacy of VCF implantation is essential for patient outcomes.
- The Braile Biomédica VCF is a newer device designed to improve upon existing technologies.
Purpose of the Study:
- To evaluate complications during the implantation of the Braile Vena Cava filter (VCF).
- To assess the efficacy of the Braile VCF's centralization mechanism.
- To compare the Braile VCF's performance with historical data, specifically the Greenfield filter.
Main Methods:
- Retrospective cohort study of 112 Braile VCF implantations from 2004-2009.
- Analysis of angiographic examinations for filter migration, opening, implantation difficulties, and centralization.
- Comparison of decentralization data with historical Greenfield filter data.
Main Results:
- No filter opening difficulties or migration were reported in 112 implantations.
- Filter asymmetry was observed in only 1 case (0.9%).
- Statistically significant improvement in decentralization compared to the Greenfield filter.
Conclusions:
- The Braile Biomédico VCF shows a high safety profile with minimal implantation complications.
- The Braile VCF demonstrates superior implantation symmetry and centralization efficacy.
- The Braile VCF represents an advancement over the Greenfield filter for embolus protection.
Abstract:
The aim of this study was to evaluate complications experienced during implantation of the Braile Vena Cava filter (VCF) and the efficacy of the centralization mechanism of the filter. This retrospective cohort study evaluated all Braile Biomédica VCFs implanted from 2004 to 2009 in Hospital de Base Medicine School in São José do Rio Preto, Brazil. Of particular concern was the filter's symmetry during implantation and complications experienced during the procedure. All the angiographic examinations performed during the implantation of the filters were analyzed in respect to the following parameters: migration of the filter, non-opening or difficulties in the implantation and centralization of the filter. A total of 112 Braile CVFs were implanted and there were no reports of filter opening difficulties or in respect to migration. Asymmetry was observed in 1/112 (0.9%) cases. A statistically significant difference was seen on comparing historical data on decentralization of the Greenfield filter with the data of this study. The Braile Biomédico filter is an evolution of the Greenfield filter providing improved embolus capture and better implantation symmetry.
